  • Publication number: 20240009320
    Abstract: The present disclosure is directed to an organogel drug depot for use in a non-sterile environment and application to a non-sterile open wound site. The present disclosure is also directed to an organogel drug depot for use in delivering an active agent to a surgical site, such as an implant site, for instance an orthopedic implant site. In a further embodiment, there is disclosed a system for preparing an organogel drug depot including an organogel matrix comprising an organogelator and a biocompatible organic solvent, an active agent comprising solid particles, a container including at least one wall having an outer surface and defining a volume capable of containing the organogel matrix and active agent solid particles, and a heating component configured to contact the outer surface and supply an amount of heat to the container.

  • Patent number: 11826333
    Abstract: Provided herein are compositions for treating biofilm-derived infections include a cis-monounsaturated fatty acid solubilized in a solvent with a concentration in the range of about 100 ppm (parts per million) to about 1000 ppm, where the composition is configured to produce a bactericidal effect measured as a log reduction of colony forming units (CFU) of a bacteria of at least 1.0 when the composition is applied to a biofilm formed from the bacteria. Also provided are methods for treating the site of a biofilm-derived infection comprising applying a composition as disclosed herein to the site.

  • Publication number: 20220370692
    Abstract: Provided are orthopedic implants and systems and kits containing orthopedic implants that include biodegradable polymer thin films containing an antimicrobial agent, wherein the implants produce an effective zone of inhibition around a periphery of the surface of the implant and do not produce a loss of release torque between interlocking implant components.

  • Publication number: 20220071677
    Abstract: The present disclosure is directed to temporary antimicrobial-eluting cement spacer implants, and assemblies, kits, and methods for forming the same. Particularly preferred disclosures are to modular spacers, assemblies, and kits, as well as methods of manufacturing the same, where the modular nature of the spacer permits the selection of specific desired length spacers, as well as specific selection of antimicrobial compounds and dosages, along with the components and processes for forming the same.

  • Publication number: 20210154374
    Abstract: The present disclosure is directed to systems, method of manufacture, and packaging configurations for an antimicrobial orthopedic implant having an antimicrobial coating on the outer surface of the implant including a vaporizable antimicrobial agent in a surface area concentration on the outer surface sufficient to prevent bacterial growth on the orthopedic implant, and can additionally provide a clinically effective zone of inhibition around the orthopedic implant. In certain embodiments, a container, a reservoir of the vaporizable antimicrobial agent, and the orthopedic implant are configured to remain thermally stable in a temperature range up to 200C.

  • Publication number: 20100166854
    Abstract: A method of forming electrospun fiber mats from a plurality of different biodegradable polymeric fibers is provided, in which a plurality of up to six different biodegradable polymer solutions are electrospun together by a method comprising the steps of providing a plurality of up to six different biodegradable polymer solutions each containing at least one biologically or pharmaceutically active material and each in communication with a needle for electrospinning a biodegradable polymer fiber from the solution, and pumping each solution through its respective needle into an electric field under conditions effective to produce uncontrolled charged jet streams of the polymer solutions directed at a grounded rotating mandrel, thereby forming fiber threads of the biologically or pharmaceutically active compounds and polymers in the solutions that are deposited on the mandrel to form an electrospun non-woven fiber mat, wherein the needles are positioned for co-deposition of the fiber threads from the polymer solu
